(This pretty much falls under the "Free Node System" suggestion: Upgrade the rigid bone system into flexible nodes and constraints like in other animation systems, where they are easily movable, scale-able, etc.)

Yes but bone length would be easier to implement, and would be more compatible with older files

Ive noticed in the latest versions that anim8or is no longer reading .mtl files. can anyone else confirm?Edit: opening the .obj file via Import still reads the .mtl file, but directly opening a .obj file no longer auto loads the .mtl file like it used to.

Actually, a correction, its only one light, but it passes through the object, since there are no shadows in the workspace renderer. the yellowish light is actually the faces being illuminated from the backside. The reason for the black stripe is that the light doesn't illuminate surfaces that it hits at or near a right angle. Well, you learn something new every day... I always believed it was one light...

run over that spot again with the weight brush, multiple bones can have the same color assigned to them, making it look like the area is connected to the right bone, when its actually connected to a different bone nowhere near it.
